Abstract

Dans un récepteur de signaux de télévision destiné à recevoir des signaux et les traiter (RF), qui comprend des signaux vidéo modulés et des signaux audio modulés, un syntoniseur (16) reçoit des signaux de télévision sélectionnés et émet au moins des signaux à fréquence intermédiaire (IF), un filtre à ondes de surface (17) est connecté au syntoniseur (16), un démodulateur vidéo (18) démodule les signaux vidéo provenant du filtre à ondes de surface (17) pour obtenir des signaux vidéo démodulés destinés au traitement ultérieur, un générateur (16) émet des signaux (SIF) comprenant les signaux audio modulés à une fréquence porteuse égale à la différence entre une fréquence porteuse des signaux vidéo modulés et une fréquence porteuse des signaux audio modulés dans les signaux de télévision, un démodulateur audio (5) démodule les signaux audio des signaux (SIF) à partir du générateur (16) pour obtenir des signaux audio démodulés destinés à un traitement ultérieur. Selon l'invention, le générateur (16) est connecté au syntoniseur (16) et le démodulateur audio (5) est connecté au générateur (16).
